Markus Armbruster 2013-08-26 19:05:45 UTC Doc Text Cause: USB host controller device piix4-usb-uhci is available in RHEL-6, but not in RHEL-7.

Consequence: guests configured with this device cannot be migrated from a RHEL-6 host to a RHEL-7 host.

Workaround: reconfigure the guest to use piix3-usb-uhci instead of piix4-usb-uhci. To do this in libvirt domain XML, replace piix4-usb-uhci in

<devices>
<controller type='usb' model='piix4-usb-uhci'>
...
</controller>
</devices>

by piix3-usb-uhci, and reboot the guest.
